Thanks CÃ©drick, this partly worked because I also had a git repository, but I noted that if the .git folder is not present the procedure don't work as well. It, however, cannot load remote dependent projects or baselines, and thus fail. :( <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> Livre de vÃrus. www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…>. <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> On Mon, Nov 12, 2018 at 5:03 PM CÃ©drick BÃ©ler <cdrick65(a)gmail.com> wrote: > Hi Vitor, > > Le 12 nov. 2018 Ã 19:53, Vitor Medina Cruz <vitormcruz(a)gmail.com> a Ã©crit > : > > Hello, > > How do I load a baseline located at disk?

OpenGL minimum working example?

by HernÃ¡n Morales Durand

Hi. I tried to get an OpenGL MWE from https://github.com/ronsaldo/uffi-opengl in both Windows 8.1 and MacOS without luck. What I tried so far is to render a simple figure in a new window, adding this method to UFFIOpenGLOffscreenSamples: >>sample2 " self new sample2 " | context gl fb | context := UFFIOpenGLContext new. gl := context gl. fb := context offscreenBufferExtent: 300@300. context asCurrentDo: [ fb activate. gl " loadIdentity;" clear: GL_COLOR_BUFFER_BIT; begin: GL_QUADS; color3f_red: 1.0 green: 0.0 blue: 0.0; vertex3f_x: 0.0 y: 0.0 z: 0.0; vertex3f_x: 0.5 y: 0.0 z: 0.0; vertex3f_x: 0.5 y: 0.5 z: 0.0; vertex3f_x: 0.0 y: 0.5 z: 0.0; end; flush ]. fb asForm asMorph openInWindow. However the result is that VM hangs in both platforms. Any advice what I'm missing? Cheers, HernÃ¡n

Iceberg + BaselinOf + Metacello - how to manage interdependencies ?

by CÃ©drick BÃ©ler

Hi all, Iâm trying to declare a BaselinOf to load lots of Packages. My aim is to have a kind of distribution (so students donât have to load packages). Iâm new to Iceberg + BaselinOf + Metacello. I target only P7. Let's say I want to load Teapot and NeoJSON (development version). Teapot depends on NeoJSON (#stable). So, whatever the order of declaration in the BaselineOfMyProject, Iâd like not to have the following conflict: So is it possible to tell to load : - Teapot , then NeoJSON (updating to NeoJSON the dependancies of Teapot) - NeoJSON (#latest) then Teapot (ignoring the NeoJSON stable of Teapot baseline). I know I risk breaking Teapot (but I donât care :), I want latest NeoJSON. So is it possible to define such constraints ? Iâm aware of that way of loading from Metacello : Metacello new baseline: 'NeoCSV'; repository: 'gitlocal://../../iceberg/svenvc/NeoCSV' ; onConflict: [ :err | err useIncoming ]; onUpgrade: [ :err | err useIncoming ]; load Still, not sure, of the meaning of #useIncoming (#allow #disallow). 1) Does one mean keep/load the latest ? 2) is it possible to launch such Metacello installation from Iceberg ? TIA, CÃ©drick

Re: [Pharo-users] Examples of bad code

by webwarrior

In old Pharo code (Morphic, etc.) there's a lot of wierd stuff. My favourite is DockingBarMorph>>#predominantDockingBarsOfChastes: Though it explains what "predominant" means in a long comment, it's absolutely unclear what the heck "chaste" is. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Examples of bad code

by Oleksandr Zaytsev

Hello, Do you know of some good examples of code that is unreadable because of the bad and inconsistent naming? I want to show some motivating example in my thesis about the aspects of software naturalness through the generation of identifier names. I'm sure that Pharo has many bad code inside, but this has to be something 1. From the real project written by experienced developers or a nice community (not some toy example or a code of bad developers) 2. With identifier names so bad that 2-3 chunks of code are enough to demonstrate how incomprehensible this code is. I need it to prove the point that 1. Bad naming can really harm the readability 2. Bad naming is not just a result of carelessness and lack of experience. Bad names often appear in successful projects and are introduced by experienced developers as a result of software evolution (many people write and rewrite the same code many times introducing inconsistencies and failing to understand each other's intentions and different parts of the system). Do you know some good examples of bad code from PolyMath, Seaside, Moose etc.? Oleks
